Based on police reports, the driver lost control of the steering wheel of the car. The vehicle crossed into the opposite lane and struck a riprap wall before swerving back and hitting a road gutter, which caused the car to overturn.
All occupants were immediately transported to a nearby hospital for medical treatment.
The collision also caused debris and rocks from the damaged road gutter to fall onto the roof of a residence located below the highway level.
Police investigators have subjected the driver and the passengers to alcohol breath tests to determine if intoxication played a role in the crash. Authorities have yet to release an official estimate of the total cost of damages to the vehicle, the residential property, and the public infrastructure.
